Universities research rice husk ash as cement alternative09 July 2024, Published under Cement NewsResearchers from ten universities across the globe are exploring the feasibility of using rice husk ash (RHA) in place of cement for manufacturing activities. The participating researchers have found the RHA has a high silica content. Therefore, when RHA is used to produce concrete, it triggers a chemical reaction with hydrates (such as calcium hydroxides). This results in the formation of supplementary products that give the mixture strength and stability, which are vital for the concr... |
